3 Claims. (Cl. 'l2-130) This invention relates to an apparatus for spreading mortar on tiers of blocks or the equivalent during the process of building a wall with blocksfand mortar.

It is particularly aimed .to ,provide a structure which is manually operable to be moved over the wall to lay mortar adjacent the front and rear thereof in ribbons or streams'of the desired width and with the mortar tempered to the right consistency and in a manner superior to the application of mortar by means of a trowel.

It is generally aimed to provide a structure which will aid in ymaterially lowering the building cost of a wall, a structure which may be made in various widths and sizes according to the particular wall to be built, and a structure wherein the amount of mortar discharged is regulable.

The more specic objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a front elevation of the spreader in connection with the upper portion of a wall;

Figure 2 is a rear elevation or end view of the spreader in connection with a wall;

Figure 3 is a longitudinal sectional view taken on the line 3-3 of Figure 1;

Figure 4 is a vertical sectional view taken on the line 4-4 of Figure 3;

Figure 5 isA a fragmentary elevation showing the use of a guide which may be employed; and

Figure 6 is a detail section taken ori the line 8--6 of Figure 2.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, I0 designates a suitable hopper or container, for instance of rectangular form and open at the top so that it may be lled with mortar. It is clear that the hopper and associated parts constituting the spreader may be built in any desired size or width according to the particular wall to be built. Said hopper is supported on a pair of sills II, for instance of channel shape, parallel to each other and the sides 'of the hopper, spaced apart and equidistant 'from the latter and extending beyond both endsof the hopper.

At the forward end of the machine, in front of the hopper, an axle I2 is rigidly mounted on the sills II, for instance being clamped in place by U-bolts I3. Journaled on the outer ends of the axle I2, are front wheels or rollers I4 preferably provided with flanges I5.

At the rear end of the device axles I6 are suitably mounted on the sills II, and rollers I1 of suitable weight are journaled thereon.

It will be clear that the rollers or wheels I4 and I'I travel along tiers of blocks I8 in the process of building a wall and that the anges I5 overlap the opposed side faces of the wall or blocks in order to guide the device during its travel. Such guiding may be augmented by means of a gauge bar I9 adjustably fastened by Wingnut 29 on a bolt 2l mounted in a side wall of the hopper. Such gauge bar I9 is adapted for operativepositioning as shown in full line in Figure 5 to engage the outer surface of the wall or blocks I8 when desired or to be elevated and fastened in an inoperative position as shown in dotted line in Figure 5.

Similar discharge gates 22 are located at the bottom of the hopper, being hinged on horizontal pintles 23 to the lower edges of the side walls. Such gates, in closed position, are inclined as shown in Figure 5, and inverted V-bottom 24 is xed as at 25 to the end walls of the hopper, the inclination of such bottom serving to direct mortar toward the gates 22 and discharge openings in the bottom wall of the hopper as covered thereby. Such bottom 24 has inwardly-extending flanges 26 secured by means of rivets 21 to the sills I I, and the rivets also preferably secure in place horizontal flanges 28 of depending aprons 29 disposed against the outer flanges of the sills II and preferably extending below the same as shown. The sills II are not only secured in place by the bottom 24 but are further secured to the hopper by L-shaped brackets, riveted at 3| to the end walls of the hopper and at 32 to the sills.

At their front ends, each gate 22 is provided with a crank 33 and pivotally connected to the cranks are downwardly diverging links 34 pivoted together at 35 to a, vertically slidable control bar 36. Such bar passes through slots 31 in a bracket 38 fastened to the front end wall of the hopper, and at the top the operating bar 3B has an outwardly extended handle 39. Bar 36 is normally retracted or in uppermost position to maintain the gates 22 closed, and it is held in such position through the engagement of a lip 39 of a latch 40 therewith, such latch being pivoted at 4| to the front end of the Wall of the hopper. The latch 40 readily may be moved manually to one side to enable the gates 22 to swing downwardly to vertical position and thus to open position. Upon restoring the gates to closed position, the bar 36 will be moved upwardly and in so doing will engage the cam or inclined surface 42 of the latch 40 in order automatically to displace the latch and come into engagement with the upper surface of the lip 39'.

When the gates 22 are vertical or in open position, the mortar will discharge from the hopper adjacent each side through the openings at the bottom, exposed by the gates, and the depth of the two ribbons or courses of mortar which will be laid through such openings on the top of the wall or blocks IB will be of a predetermined depth, governed by the height of 'gauges 43 ha'ving vertically elongated slots 44 through which bolts 45 pass adjustably to secure the gauges against the rear wall of the hopper. At the bottoms, the gauges 43 may have rearwardly extending flanges 46, and at their tops or upper ends they may have handles or grips 41.

A handle 48 is preferably fastened to each end wall adjacent the top thereof to enable eiiicient handling and manipulation of the device in use.

Various changes may be resorted to provided that they fall within the spirit and scope of the invention.

I claim as my invention:

1. A device of the class described comprising a hopper, discharge gates at the bottom of the hopper, a bottom structure in the hopper between said discharge gates, means mounting said gates for opening and closing to discharge mortar, means mounting the hopper for movement over blocks in the building of a wall, the last mentioned means comprising sills on which the hopper is disposed and to which the gates incline in closed position, and roller means mounted by said sills.

2. A device of the class described comprising a hopper, discharge gates at the bottom of the hopper, a bottom structure in the hopper between said discharge gates, means mounting said gates for opening and closing to discharge mortar, means mounting the hopper for movement over l blocks in the building of a. wall, the last mentioned means comprising sills on which the hop? gates for openi g and closing to discharge mortar.

and means mo ting the hopper for movement over blocks in t e building of a wall, comprising sills on which he hopper is disposed and to which the gates incline in closed position, and

axles and rollers mounted by said sills, said bottom structure having inwardly extending flanges disposed over the sills, and aprons depending below the outer faces of the sills having inwardly extending anges secured between the first-mentioned iianges and the sills.
